Safety razor



SAFETY RAZOR Filed Dec. 19, 1934 llllllhi WITNESSES INVENTOR Y i717/ [am lYar/mv/M BY l WW man (j Patented Nov. 5, 1935 UNITED STATES APATENT OFFICE 2 Claims.

This invention relates to safety razors, and the primary object of the invention is to provide means whereby the blade may be turned over so that the edges of first one side and then the other can be used as often as it is'desirable to from their normal positions when screwed to-v gether, to a position which will allo-w the blade to be turned over and provide means for permitting the turning of the blade, said means also constituting an attached part of the razor assemblage, so vthat it is not necessary to touch the blade with the operators lingers or thumb on turning theblade over from side to side, and in assembling or separating the parts.

` Withithese and other'objects in View, the invention consists in certain novel features of construction and combinations and arrangements of parts, all of which will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawing- Figure 1 is an end view of the safety razor looking down upon the clamp or cap, and guard;

Figure 2 is a view in longitudinal section on the line 2-2 of Figure 1, illustrating in dotted lines raised positions of the clamp and blade;

Figure 3 is a fragmentary view in side elevation of Figures 1 and 2;

Figure 4 is an enlarged fragmentary detail View illustrating the blade holder and its mount- 111g;

Figure 5 is a fragmentary plan view partly in section, illustrating the blade holder with the blade in position thereon; and

Figure 6 is a perspective view illustrating the position of the parts and the manner of manipulating the same to turn the blade over.

In Figures 2, 3 and 6, I represents the tubular handle of the razor to one end of which a toothed guard 2 is fixed. 'I'his guard 2 has teeth or notches 3 at both side edges, as is customary in the manufactureV of safety razors, and is provided with a central opening 4 registering with the tubular handle I and with openings 5 at opposite ends thereof. 6 represents a clamp which is provided with a central pin 'I to enter the central opening'd and with other pins 8 to enter the openings 5. The center pin I is illustrated with a screw threaded socket 9 toreceive a threaded stud I0 upon the inner end of a tubular stem Il located in the tubular handle I. The stem II has an enlarged milled outer end I 2 and is formed with. a collar I3 within the handle I, which engages an annular internal shoulder I3 to limit the longitudinal movement of the stern but permit v5 the free-turning movement thereof. This hollow stem I2 has one or more openings I5 therein through which water or air can pass so that when the end of the stem isY subject to a flow of water or a blow of air the water or air will pass between 10 the guard'and clamp to clean the razor.

In the particular illustration I show a razor having a transversely arched or channeled guard and clamp for the free passage of air and water, but it is to be distinctly understood that this par- 15 ticular invention is not limited to the particular form o f guard, clamp, handle and stem, and these parts can be varied in construction and the invention still apply.

The reference character I6 is employed to indi- 20 cate `Va razor blade which has a plurality of cutting edges and which is flexible and which may be provided with holes through which pins 1, 8 and 9 may go, so thatfit may take proper shape between the guard and clamp. At one end of 25 the guard I provide what I term a blade reversing holder which constitutes a clip or clamp Il in which one end of the blade I6 or any part o blade vI6 can be positioned and securely held. This clip or clamp may be longer or shorter than the one shown and may have holes through which pins l, 8 and 9 may go. It may be of any shape which may be necessary to hold the blade in position, whether lying between the guard and the clamp or whether it is being lifted when the blade is to be turned over. This holder I'I also has a journal I8 mounted to turn in a bearing I9 in a bracket 28, and a milled head 2| is formed on the holder at the outer end of the journal I8 to facilitate the manipulation thereof. 'Ihe bracket 20 is pivoted, as s'hown at 22, within a slot 23v at one end of the guard so that when the clamp is suiiiciently elevated the operator can grasp the milled head 2| between the thumb and finger, raise the blade to an elevated position, as indicated in Figures 2 and 6 of the drawing, and then turn the blade so as to present another side of it to the guard and the blade put into proper position thereon for shaving. The clamp 6 is formed with a recess 21 at one end to accommodate the bracket 26 when the parts of the razor are in normal position for shaving.

The clamp 6 is connected to one end of the guard 2 in such a manner as to not only permit the clamp to be hinged or pivoted but also to 55 permit a certain amount of longitudinal movement or play of the clamp relative to the guard to insure an easy release or tightening of the pins 'I and 8 between the blade and guard. In order to accomplish this I have illustrated one means which includes the provision of a link 24 which extends through an opening 25 in the guard, and has a cross pin or stop 26 at its lower portion limiting the upward or outward movement of the link. The other extremity of the link is pivotally connected to one end of the clamp, as shown at 21, and is preferably located within the slot 28 in the clamp.

Figures 1 and 2 of the drawing illustrates the normal position of the parts with the razor in condition for use. When it is desired to turn over or reverse the blade E it is simply necessary to unscrew the stem I2 to release the stud IU and pin 1, or in the alternative to unscrew the stem I2 to release the pin 1 from the stud I0 in case it is decided to put the threads on the outside of the pin 'I and on the inside of the stud I0. The clamp can then be first moved in parallelism with the guard sufficiently to release the pins 1, 8 and 9 from the blade and guard, and then the clamp can be swung upwardly or away from the blade and the guard and be disposed at an angle thereto, as indicated in Figure 6 of the drawing. The operator can then grasp the milled end 2l between the thumb and finger and raise the blade IG up from out of contact with the guard, and can then turn the milled end of the blade holder so that an opposite or reverse side of the blade can be presented to and positioned upon the guard. The clamp can then be returned downward to its position parallel with the guard and be secured by means of the stud I at the end of the stem I2, as can be readily understood.

In the drawing I have illustrated a razor and blade having a particular type of opening or slot therein which accommodates the pin 1, 8 and 9, but it is to be distinctly understood that this invention is not limited to any particular arrangement of openings except that it is, of course, necessary that the razor and blade have openings through which the pins can project.

While I have illustrated what I believe to be the preferred embodiment of my invention, it is to be distinctly understood that various slight changes may be made with regard to the form 10 and arrangement of parts without departing from my invention, and hence I do not limit myself to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of the claims, especially as to the means of opening or closing the parts so as to leave the blade free to be reversed or turned from side to side.

What I claim is:

1. A safety razor including a guard having teeth at both longitudinal edges, a cap pivoted to one end of said guard, a blade clamp pivoted to the other end of said guard and adapted to receive and clamp one end of a two edge blade, said clamp having rotary mounting in its pivotal support so that when said cap is moved away from the blade and the guard and the blade moved at an angle to the guard the blade may be manually turned.

2. A safety razor including a guard having teeth at both longitudinal edges, a cap pivotally connected to one end of the guard, a bracket pivotally connected to the other end of the guard,

a razor clamp having rotary mounting in the bracket and adapted to clamp one end of a two edge blade and a milled head on the blade clamp adapted to be grasped between the thumb and fingers of an operators hand to turn the clamp and blade when the blade is moved at an angle to the guard.
